A mayor in France’s northern Oise region is leading the charge to improve politeness by introducing a law forcing people to remember their Ps and Qs.

A poll earlier this year revealed “lack of manners” was the number one cause of stress for 60 percent of French people and Gerard Plée, the mayor of the small town of Lhéraule, to the north of Paris, has taken action to ease that anxiety for the 185 residents.

From now on, visitors to the town hall will be asked to leave the building if they do not say ‘hello’ or ‘thank you’ to staff.

The decree, designed to enforce “social standards in the municipality”, will be applied when there is a “concrete example” of a breach of courtesy.
